specific rotary power

Japanese: specific rotatory power（英語表記）specificrotatorypower

…This is a value that is unique to a substance, and is a useful quantity for studying the molecular structures of organic compounds with asymmetric atoms, metal complexes, and organometallic compounds. Optical rotation is expressed as the angle of rotation of the polarized light plane (angle of rotation), but since the angle of rotation is generally proportional to the thickness of the layer of the optically active substance or the number of molecules of the optically active substance, the specific rotation power is used as the quantity unique to a substance. (1) Specific rotation is expressed as the angle of rotation α degrees. …

Japanese:

…これは物質に固有な値を示し，不斉原子をもつ有機化合物，金属錯体や有機金属化合物などの分子構造を研究する有力な量となる。旋光度は偏光面の回転した角度(旋光角)で表すが，一般に旋光角は旋光性物質の層の厚さ，ないしは旋光性物質の分子数に比例するので，物質に固有な量として比旋光度specific rotatory powerを用いる。(1)比旋光度は，旋光角をα度として，で表される。…
